I have a Swing application and we are having a problem with some Mac users and
The tables have this selection mode set:
On Windows with this selected you can:
- select a single row
- select contiguous rows by holding the mouse and dragging
- select contiguous rows by clicking the first row to select, pressing shift and clicking the end row to select
- Select multiple groups of contiguous rows by clicking a row and drag and then holding ctrl and doing it again from a different row
- You can hold Ctrl down and individually select rows that are Not contiguous
On Mac OS you can only do 1 and 2. I don’t care about 3 and 4, but I really need them to be able to select random rows that are not contiguous.
I generated this on windows using the standard JTable simple demo. You can’t do so on Mac. You can on linux. Here is the link to that demo: docs.oracle.com/javase/tutorial/uiswing/components/table.html
Is this a known problem or is there a solution known?
The Windows Ctrl key is closer in function to Mac’s Command key, not the Control key, despite Java recognizing Win’s Ctrl key & Mac’s Control key as having the same KeyEvent#getKeyCode() value of 17.
Selecting non-contiguous rows worked for me by holding down the Command key, not Control. Tested on a MacBook Air with an M1 chip running MacOS Monterey 12.0.1, using Azul Zulu’s Build of the OpenJDK version 17.0.2.
